Description

This reference design is intended for Passive Entry Passive Start (PEPS) car access systems that utilize Bluetooth® Low Energy (BLE) technology to determine the location of a key fob. The design exhibits how a vehicle BLE satellite node can be implemented to calculate the angle of arrival (AoA) from a BLE signal and transmit the AoA data via local interconnect network (LIN) using only a single BLE wireless microcontroller and LIN transceiver. Furthermore, the design demonstrates that accurate AoA information can be calculated using only two dipole antennas reducing the printed circuit board (PCB) solution size.

Features
  • Measure AoA using BLE with only 2 dipole antennas
  • Share BLE connection information, AoA and RSSI information via LIN
  • Small 45.72 mm × 76.2 mm (1.9" × 3.0") PCB solution size
  • Low-power sleep mode with remote wake over LIN < 25 µA at 14 V
  • DC input voltages from 4.65 V to 40 V and load dump voltages up to 45 V
  • Compatible with TI's Real Time Locationing System (RTLS) software toolbox for triangulation and trilateration of a BLE key fob
